This collection contains manuscript notes, lists, and catalogs concerning bird specimens. The catalogs are the primary documentation for many of the specimens of the
Division of Birds. Although they vary in content, as a general rule they contain specimen-related data including catalogs of specimens collected, dates, localities, tag numbers,
measurements, and remarks on the specimens. Less frequently, they contain journal entries of the collector describing field activities, affairs of the day, anthropological
observations, personal financial accounts, and other personal matters. Also included is an edited manuscript on Arctic birds, apparently compiled from the notes of Bernard
Rogan Ross, Roderick Ross MacFarlane, Robert Kennicott, and others.
